Rubber crumb binder 4.5kg. (One-component Single pack)
For the production of the ultimate safety/comfort surfaces.

An MDI based polyurethane prepolymer for use as a rubber crumb binder. It has a relatively low viscosity
and its fast cure speed is ideal for play areas.
This product has been formulated as a flexible moisture curing binder for in situ recycled rubber crumb
shock pads and EPDM play surface top coats, which are laid by hand.

Rubber crumb binder (One-component Single pack)  4.5kg.

Shock Pad Base Layer / Top Coats
Mix rubber granules and binder at desired ratio.
Typical addition of 12% for the Base layer and 18% for the Topcoat (wear) surface.

Ensure the volumetric ratio of binder addition is considered as the bulk density of rubbers will vary. Rubber granules should be dry in order to stop accelerated cure times and foaming of the binder.
For adequate mixing, a high torque rotary mixer should be used. Rubber and binder should be mixed for upto 5 minutes ensuring all the rubber is coated.
The product can then be laid out on a prepared surface and compacted using a hand trowel or weighted roller. Ensure an even compaction of the rubber. A release agent should be used on all tools to avoid adhesion of the binder to the tools.

Ensure all equipment is cleaned well after use.
In some cases, particularly low temperatures, Rubber Crumb Binder (PU Accelerator) may
need to be added.
